The current algorithm doesn't take into account that roads with
access=private or which have barriers on them with access private
should be passed through, by default:

http://mkhasanov.sandbox.cloudmade.com/directions?lat=44.42775&lon=25.99423&zoom=15&layers=B000FTFTT&travel_mode=car&waypoints=25.98,44.43,26.01013,44.43377

And, as Maarten said, the Permalink is not precise enough, it should
provide 5 decimals to be effective in locating a point.


Another problem is that the default shortest route for cars should
probably avoid tracks, or a "shortest on paved roads" algorithm should
be provided.

Problem visible here:
http://mkhasanov.sandbox.cloudmade.com/directions?lat=44.3905&lon=26.0228&zoom=13&layers=B000FTFTT&travel_mode=car/shortest&waypoints=25.99,44.41,25.99,44.38

Also, the fast and short route could be the same if the difference
isn't noticiable like above, where both the fast and the short route
are allegedly 4.7km long.
